Abstract

Each of the traditional niche overlap statistics requires the estimation of a density function (the so-called resource utilization function) and the result depends heavily on the arbitrary choice of the bin size or bandwidth. The author proposes an original two-dimensional niche overlap index which does not require the direct estimation of the resource utilization function, hence does not depend on the arbitrary choice of the bin size. The method measures a real two-dimensional overlap, not the overlap of one-dimensional "shadows' (marginal distributions). -from Author
